The capacity value of a generator is the contribution that a given generator makes to generation system adequacy. Due to the variable and stochastic nature of wind, the modeling of wind generation in the same manner as ...

As power systems evolve to incorporate greater
penetrations of variable renewables, the demand for flexibility
within the system is increased. Combined Cycle Gas Turbines
(CCGTs) are traditionally considered as inflexible ...

Certain developments in the electricity sector may result in suboptimal operation of base-load generating units in countries worldwide. Despite the fact they were not designed to operate in a ﬂexible manner, increasing ...

The growth of wind power as an electrical power generation resource has produced great benefits with reductions in emissions and the supply of zero cost fuel. It also has created
challenges for the operation of power ...

Capacity credits are widely used to quantify the
ability of different generating technologies to support demand.
Most practical capacity credit calculations are based on detailed
risk modelling, however a wide range of ...

As power systems evolve to incorporate greater
penetrations of variable renewables, the demand for flexibility
within the system is increased. Combined-cycle gas turbines are
traditionally considered as relatively ...

Long-term power system planning is beset by a
trade-off between detail and scope: The chosen approach usually lies somewhere between modeling a great many generation
portfolios coarsely and very few in a more detailed ...

The concept of capacity credit is widely used to quantify the contribution of renewable
technologies to securing demand. This may be quantified in a number of ways; this paper
recommends the use of Effective Load ...
